Call on help file

[leothebuilder]

I have a dcl and lisp file that I have cobbled together and it works for the most part.

The only thing I can't figure is how to call on the help file from the "help" tile in the dcl.

The other thing I would like to do is constrain some of the input into the dialog box.

For example, in some tiles I want to restrict the maximum value that can be entered to 30, or if a value of greater

than 30 is entered the value will default to 30 (maybe with a warning message).

In other tiles I want to restrict the maximum value that can be entered to 20.

Any value entered by the user less than 20 should default to 0 (zero).

Again maybe with a warning message.

1. Have you looked at the (help) function?

[leothebuilder]

I just did and I think I am getting close.

I added the help funtion but when clicking the help button the application freezes/

Got it resolved.

I added the following directly in the dcl:

: button {
fixed_width=true;
width=13;
height=2.2;
key="help";
label= "Help";
action = "(help \"S:/IBC/Lisp/FrtHelp.htm\"\)";
}

...and when this is used on a laptop while flying 30,000 feet in the air cross country, will this still work?
I personally use alert box(es) so as to make all as a stand-alone command without any external referencing or external executing.

You might have a look at the setfunhelp function for another alternative

I see what you're getting at about "portability" and referencing a network drive.

In this instance there are graphics in the help file which is too much for an alert box.
